SPECIFICATION forming part of Letters Patent No. 728,519, dated May 19, 1903.

Application led August 16, 1902. Serial No. 119,848. (No model.)

To all whom it may concern:

Be it known that I, HENRY TSCHERNING, a citizen of the UnitedStates of America, residing at Freeport,in the county of Stephenson and State ot' Illinois', have vinvented certain the cork, the carrier and nut then movingy down, keeping the same distance apart untilthe nut reaches the bottom of the guideway,

and the carrier then running down to the bottom and screwing into the cork. This is'` the devices whiohare used to cause the corkscrew-carrier and the nut to preserve theproper relative positions-that is to say,v the devices which lock them together during the first half of their upward rmovement permit them to separate during the second half 'of the upward movement', keep them at a constant distance apart during the firsthalf of the downward movement of thecarrier, and

permit them to come together during the last half of the downward movement of the carrier. Hitherto the practice has been to use a system of positive locks between the corkscrew-carrier and the threaded nut, two hooks or some similar device Abeing usually used.

In my puller I dispense with oneof these hooks, replacing the positivelock between y the carrier and the nut bya different device, which will be explained in due course.

My invention is fully illustrated in the drawings accompanying this specification and fully described in this specification.

In the aforesaid drawings, Figure l is an elevation of the parts ot' my improved puller, .one of the .side plates' of the case being removed and the nutand corkscrew-carrier be.

` ing shown in central longitudinal section. In Fig. l the parts are shown atv the endet the stripping motion. Fig. 2 is aview similar to Fig. 1, all the parts, however, beingin elevation except the lower end of the hook on the nut, the parts in this figure being shown just 3 is a vertical section in line 3 3 of Fig. l looking in the direction of the arrow. Fig.

\6o' at the beginning of the pulling stroke. Fig.v

4 is a section in the line 4 4 of Fig. 2 looking l down. Fig. 5 is a section through the corkscrew-carrier; andv Fig. 6 is a front external .View of the puller, the case beingin position. i

In the drawings, A is the case of the corkpuller, made inthe usual form from two pieces A A2.' These two pieces are so formed as to leave two openings an. on the front side of the case, these openings being separated by a stop a2. A- longitudinal guideway o3 extends throughout the greater portion of the length of the case. In this guideway runs a nut B, threaded in the usual way to permit the corkscrew'to run through it and provided with a lug b, extending into the opening ot' and adapted to engage the stop a2 at the upper end of this opening. It is obvious, of course, that the nut is free to move under proper impulse up and down through the guideway, its motion 'downward being-limited by the guideway and movement in the opposite direction being limited 'by engagement of the lug b with-the portion 0.2.? A-corkscrew-carrier C runs in the guideway a3 above .the nut B, and yin' this corkscrew-carrier is secureda corkscrew D of the ordinary type, which rnns,as

heretofore mentioned, through a suitablythreaded portion in the nut B. The corkscrew D is of course rotatable in the corkscrew-carrier C in the usual way. A leverE lock thenut and corkscrew together during a certain portion of the movement. This hook b' has its upper end pressed toward the path of the carrier by a spring b2, confined in a suitable chamber in the bottom of said hook. A pin a, projecting from the interior of the case A, is in the path of a beveled surface b3 upon the hook b', and its object is to unlock the hook from the carrier when the nut reaches its upper limit of motion. So much of its operation will be readily understood.

Starting with the nut at the bottom of the guideway and the carrier half-way down the guideway and moving downward, the operation for the first three stages is obvious. The corkscrew-carrier approaches the nut and the vcorkscrew D is rotated by the threads in the nut B, and thereby forced into the cork. The parts eventually reach the position shown in Fig. 2, when the hook Z1' latches over the projecting portions c of the carrier C and locks the nut and carrier together. The handle is then moved in the opposite direction and the carrier is raised, dragging the nut with it. The corkscrew, it will be seen, cannot rotate, and it therefore pulls the cork. When the nut reaches its upper limit of lnotion, its progress is arrested and at the same time the hook b is released by the pin a4 and the corkscrew-carrier is free to move on alone, which it does, the corkscrew D being rotated in the reverse direction by the threads in the nut B, thereby stripping the cork from the corkscrew.

The improvement illustrated herein concerns the fourth stage of the motion-thatis, the motion from the position shown in Fig. l to a position wherein the nut and carrier are the same distance apart, but where the nut is at the bottom of the guideway. In order to insure that the two parts-that is, the nut and thecarrier-preserve the proper relation, it hitherto has been customary to provide a lock between these parts which keeps them at the requisite distance. I have discovered, however, that the same thing can be accomplished by preventing the rotation of the corkscrew in the corkscrew-carrier, the positive locking device being thereby dispensed with. I use, therefore, a friction d evice in the carrier C, bearing upon the head of the corkscrew D. This head is provided with a cylindrical portion el, against which bears a preferably -cylindrical block F, pressed toward said corkscrewhead by a coiled spring F", said spring being held in place by a screw-cap F2 in the corkscrew-carrier. This cylindrical block exerts sufficient pressure upon the head of the corkscrew to prevent its easy rotation. As a result, therefore, the corkscrew-carrier, corkscrew, and nut are held in the relative positions shown in Fig. 1 until the nut reaches the bottom of the guideway. When that occurs, the tendency of the corkscrew to rotate in the carrier is of course greatly increased, and it overcomes the friction of the cylindrical block. The distinction between the construction herein shown and the positive lock construction will be quite obvious. In the old form the rotation of the corkscrew in the downward motion was prevented by locking the corkscrew-carrier and nut. In my form the locking of the corkscrew-carrier and nut is effected by preventing the rotation of the corkscrew. The simplicity and desirability of this form will be instantly appreciated.

I realize that considerable changes can be made in the details of construction, and I do not, therefore, desire to limit my invention to the exact construction shown.

I claim as new and desire to secure by Letters Patentl.
